STEAMING-VALVE MECHANISM FOR PRESSING MACHINES.

Application filed April 29, 1927. Serial No. 187,631.

This invention relates to garment and laundry pressing machines particularly garment pressing machines, and has for its objeet a particularly simple, efficient, durable and easily operable valve mechanism on the movable head of the machine for controlling the flow of steam through the ironing face of the head to steam the garment being pressed.

The invention consists in the novel features to and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters represent corresponding parts in all the views.

Figure 1 is an enlarged fragmentary sectional view of the head of a pressing machine provided with this valve mechanism.

Figure 2 is a fragmentary elevation look- 50 ing to the left in Figure 1, parts being shown in section and being omitted.

Figure 3 is a horizontal sectional view through the valve casing block.

Figure 4 is an enlarged detail View of the rack and pinion mechanism between the operating shaft and the valve rod.

Figures 5 and 6 are respectively a fragmentary side elevation and a front elevation of a pressing machine provided with my invention, parts being omitted, and Figure 5 being partly in section.

In pressing machines having a valve on the head for controlling the flow of steam from the steam chamber of the head through the pressing face, the valves usually become leaky in a very short time unless a very strong spring is employed and if a strong spring is employed the operation of the valve has heretofore been arduous and requires more than an unconscious effort of the operator.

This invention comprises a valve casing the usual lower pressing element or buck 1 mounted on a suitable frame 2. and a head 3 movable toward and from the buck and carried by a yoke or lever 4 pivoted at 4 between its ends to the frame, the yoke being actuated in any suitable manner. The head 3 is formed with a steam chamber 5 to which steam is supplied in any well known manner. The head is also formed with a line of jet openings, one of which opening is shown as 5 opening through its pressing face and with a channel 6 common to all the jet openings, the channel 6 being separated by a wall 7 from the interior of the chamber 5. The jet openings 5 are preferably provided in a plate 8 flush with the ironing face and fitted in the open side of the channel 6.

The valve mechanism includes a block or casing 9 having an internal valve chamber 10 and a .seat 11 in said chamber, the block having a base 12 having a lower flat face complemental to an upper fiat face 13 on the upper side of the head 3, the base being secured to the head in any suitable manner. The valve chamber 10 extends in'a horizontal direction forwardly and rearwardly and includes a receiving portion 14 on the opposite side of the valve seat 11 to that on which the valve is located, and is also formed with an upright inlet passage 15 on one side of the chamber, and an'upright outlet passage 16 on the other side of the chamber, both ofthese passages opening through the lower face of the base 12, the inlet 15 beingconneeted by a passage 17 to the receiving chamber 14. The passages 15 and 16 are alined with passages 18 and 19 formed in the head and communicating respectively with the steam chamber 5 of the head and with the channel 6.

19 is a valve movable horizontally in the valve chamber 10 and pressed toward the head 11 by a relatively powerful spring 20. 21 is a valve rod extending forwardly horizontally from the valve 19 through suitable passages in the valve block, the passage 22 being closed by suitable gland 23.

The valve rod 21 is provided with an enlargement 24 at its front end which slides in a suitable guide provided in a support or block 25 mounted on the head. The operating means for this rod comprises a rock shaft 26 mounted in a bearing 27 on the block 25, and a handle 28 on the rock shaft, the rock shaft and the rod or the portion 24 thereof having coacting means for transmitting the motion of one part to the other. This means is here shown as a single tooth rack 29 on the rod and a two toothed pinion 30 mounted or formed on the shaft. The bearing for the shaft is formed in a plate 31 mounted on the upper face of the block 25 and secured thereto in any suitable manner, this plate 31 also holding the rod or the port-ion 24 thereof in its guide. The block 25 is secured to the head by any suitable fastening means.

OWing to the block 9 and also the block 25, the valve and valve mechanism is readily applied to the head and owing to the horizontal position of the sliding valve and the valve chamber, leakage of Water of condensation is avoided and owing to the arrangement of the valve rod and handle whereby a straight line pull through leverage is applied to the valve the operation of the valve having a relatively strong spring for seating it, is accomplished with a minimum effort on .the

part of the operator.

What I claim .is:

In a pressing machine, the combination of a buck and ahead movable toward and from the buck, the buck having an internal steam chamber and jet openings opening through its pressing face, a channel common to the jet openings, the Wall of the channel extending into the steam chamber and separating the steam chamber from the channel, a by-pass connecting the steam chamber and opening directly into the channel, a block mounted on the head in which the by-pass is formed, a Valve carried by the head normally closing-the by-pass and a manual for operating the valve.

In testimony whereof, I have hereunto signed my name at Syracuse, in the county of Onondaga, and State of'NeW York, this 31st day of January, 1927.
